The role of staphylococcal lectins in human granulocyte stimulation
Abstract
The anti-staphylococcal activity spectrum of human polymorphonuclear leucocytes (PMN) is widely ranged. Using chemiluminescence measurements, the opsonin-independent stimulation of PMNs from eight healthy humans towards two Staphylococcus saprophyticus strains (S 1 and S 35) was investigated. Strain S 1 was shown to have surface lectins with N-acetylgalactosamine specificity, whereas strain S 35 had N-acetyl-neuraminic acid specificity. Three different PMN-reaction patterns could be demonstrated: PMN stimulation was either sensitive to N-acetylgalactosamine-or N-acetylneuraminic acid-blocking, or resistant to both. These results point to the importance of lectins for staphylococcal-PMN interactions.
